The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Rubble Pile Asteroids (2018, background): “…satellites, suggesting that this is an end-state of a spin-up and binary formation process (Walsh et al. 2008, Harris et al. 2009, Scheeres et al. 2016), but is also found around at least one non-binary with moderate spin - Bennu the target of NASA’s OSIRIS-REx mission (Lauretta et al. 2015,2017).”
OCAMS: The OSIRIS-REx Camera Suite (2017, background): “Many of the definitive campaigns that will gather the information needed to enable successful sampling require the spacecraft to orbit near the solar-terminator (Berry et al. 2013, 2015; Beshore et al. 2015; Lauretta et al. 2015; Williams et al. 2018).”
In search of the source of asteroid (101955) Bennu: Applications of the stochastic YORP model (2015, background): “sets of published thermal observations (ground-based N-band, Akari IRC, and Spitzer IRS), Mueller et al. (2011) derived an effective diameter of 0:87 0:03 km.”
Properties of rubble-pile asteroid (101955) Bennu from OSIRIS-REx imaging and thermal analysis (2019, background): “Likewise, our understanding of Bennu's global properties was inferred from telescopic observations of the asteroid as a point source [1].”
